RESUMO

This thesis describes the procedures involved in the montage, calibration and installation of 80 (eighty) electro-levels on the concrete face of Mazar¿s dam, located in the Paute river, southeast of Ecuador. This dam consists of a Concrete Face Rockfill Dam 166m high and it has upstream slopes of 1.4(h):1.0(v) and downstream slopes of 1.5(h):1.0(v). The rockfill volume is 5000000 m3. Electro-levels were installed throughout 4 sections on the concrete face in different phases of the dam construction, allowing the behavior observation of its concrete face since the beginning of the construction. For the interpretation of the results, some routines were developed to allow not only the automation of the process but also the development of graphic interface for following the process. The results indicated with precision the face displacements and showed critical regions related to the bending moment, which confirms the importance of monitoring the concrete face during all the construction stages.
